Adoption of 2017 Individual Performance Goals

On February 20, 2017, the Compensation Committee adopted individual performance goals (“IPGs”) for our named executive officers. We expect that 20% of each executive’s cash award under our 2014 Key Officers Incentive Plan will be based on the achievement of the IPGs and will be included in the 2017 award formula adopted by the Committee at the end of March 2017. The IPGs for our named executive officers¹ for 2017 are:

Karl G. Glassman: Strategic planning and succession planning;

Matthew C. Flanigan: Strategic planning, information technology improvements, succession planning and efficiency initiatives;

Perry E. Davis: Growth initiatives and succession planning; and

Jack D. Crusa²: Mr. Crusa was not assigned IPGs for 2017.

The achievement of the IPGs is measured by the following schedule.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On February 21, 2017, the Board of Directors of the Company, on recommendation of the Nominating & Corporate Governance Committee, approved an amendment and restatement of the Company’s Bylaws, to implement proxy access as a means for the Company’s shareholders to include shareholder-nominated director candidates in the Company’s proxy materials for its annual meeting of shareholders if certain qualifying conditions are met, and make certain refinements and conforming changes to the advance notice provisions for the requirements for shareholder business at an annual meeting contained in Section 1.2(b) of the Bylaws, and shareholder nominations contained in Section 2.2(b) of the Bylaws, and make certain other updates. The amendments were effective upon approval, with proxy access first being available for the Company’s 2018 Annual Meeting of Shareholders.

The amended Bylaws add new Section 2.2(e) that permits a qualifying shareholder, or a group of up to 20 such shareholders, owning at least three percent of the Company’s outstanding stock continuously for at least three years to nominate, and include in the Company’s annual meeting proxy materials, qualifying director nominees constituting up to the greater of two directors or 20% of the Board, provided that the shareholders and nominees satisfy the eligibility, procedural and other requirements specified in the Bylaws. The Board’s decision to adopt the proxy access amendments followed the Board’s review of evolving governance practices and engagement with shareholders.

With respect to the advance notice provisions, in addition to conforming changes to reflect proxy access, the Bylaws were updated to provide a mechanism for updates and supplements of required information to ensure that the information provided in such notice is true and correct not only as of the date originally received by the Company, but also as of the record date for the annual meeting of shareholders and as of the specified date prior to the annual meeting.

The amended Bylaws also provide that special meetings of the Board of Directors may be called by any of the Board Chair, the Lead Director, the Chief Executive Officer, the President or at the written request of three or more directors.

The preceding summary is qualified in its entirety by reference to the Bylaws, as amended through February 21, 2017. The Bylaws, as amended, and a copy of the amended provisions marked to show changes from the prior provisions, are included as Exhibits 3.2.1 and 3.2.2, respectively, to this Current Report on Form 8-K and are incorporated by reference.
